OK, I'll remove GLOBAL_TARGETs completely from the output. You can already
limited the target types that are going to be listed, and I intended to use that
mechanism to suppress GLOBAL_TARGETs when using the daemon-mode from Qt Creator.

I just renamed the target's "buildDirectory" to "artifactDirectory". It is
populated like this:
    const cmGeneratorTarget::OutputInfo* output =
      target->GetOutputInfo(config);
    if (output) {
      result[ARTIFACT_DIRECTORY_KEY] = output->OutDir;
    }

I assume that is the directory where (main?) artifacts will end up in?

Should I dump the other values of OutputInfo, too?

I will look into that next.
